This page contains Summary Notes for how I was able to install J802 onto some Training PCs running Linux Mint Xfce. These notes are specific to J802 – so some variation of the below might be needed to install earlier versions of the J Programming Language.

Mint 13 is based on Ubuntu 12.04 LTS … so hopefully this will help with all Linux Distributions that are based on 12.04 LTS.

• In the Terminal window run (copy & paste) the following command:

• sudo apt-get install libqtcore4 libqtgui4 libqt4-opengl libqtwebkit4

Now continue by following the instructions to install J in Mint 17 Xfce.

Mint 17 is based on Ubuntu 14.04 LTS … so hopefully this will help with all Linux Distributions that are based on 14.04 LTS.

• Download the Linux install file for J and run the Linux Installer
  • http://www.jsoftware.com/download/j802/install/
    • Download the correct (32bit or 64bit) .deb file for J802
    • In the Downloads directory, double click on the (just downloaded) .deb file, and install it.

• Now run Jconsole using sudo – to provide the necessary permissions to then install the rest of the J language files and JQt IDE
  → In the Terminal window run (copy & paste) the following command:

• sudo /usr/bin/ijconsole

  • Jconsole is now running in the same terminal window the above command was run in. So in Jconsole, run (copy & paste) the following commands:

  • install 'all'
    exit ''

• Now mark the files that will be used to run Jconsole and the JQt IDE as executable
  → In the still open Terminal window run (copy & paste) the following commands:

• cd /usr/share/j/8.0.2/
  sudo chmod +x *.desktop
  exit

• And finally create the Desktop Links to run Jconsole and the JQt IDE
  • Using the Thunar File Manager go to → File System » usr » share » j » 8.0.2
  • Using the top-of-window menus → View » View as Detailed List
  • right-click Jconsole (w/ Green “J” icon) » Send To » Desktop (Create Link)
  • right-click JQt IDE (w/ Green “J” icon) » Send To » Desktop (Create Link)

• Jconsole can be run using either “Menu” icon » Development » Jconsole or the Jconsole icon on the Desktop
  • The A Taste of J (part 1) and A Taste of J (part 2) introduction/example code all works

• JQt IDE is run using the Desktop Icon
  • The top (1st) Example Code from http://www.jsoftware.com/jwiki/Studio/Viewmat can be run as follows:
  • top of window menu » File » New temp (or type Ctrl-N)
  • In the window that opened, Copy & Paste the following lines into the Green text area of that window

    require 'viewmat'
    hp=: 3 : '(|.,]) 1 (0 _2 _2 ,&.> _2 _1 0 + #y) } (,.|:) y'
    MG=: 256 #. 128 0 128,:0 192 0
    viewrgb 2 ([ # #"1) MG {~ hp ^:6 [ 0, 0 1 0 ,: 0

  • Select the Green Triangular “Run” icon (Run All Lines)
    • This should open a new window with the results image shown below:

• jqt ubuntu … for J801 → “Linux jqt was built with Qt4.8”
